The ELKHART PRODUCTS 1-1/4" COP is a wrot copper coupling without stop, designed for sweat-solder copper pipe connections in plumbing and mechanical systems. The absence of an internal stop allows the fitting to be repositioned along the pipe during repair work, making it a practical choice when working in tight retrofit situations. At 0.149 pounds and compact overall dimensions, this coupling is rated for standard residential and light commercial copper piping applications. It uses a C x C (copper-to-copper) connection type and is joined using a solder process consistent with ASTM and ASME plumbing standards. Licensed plumbers and pipefitters are the primary installers.
This coupling is suited for residential and commercial potable water distribution, hydronic heating systems, and general-purpose copper pipe repairs where a solder-joint fitting without an internal stop is required. The C x C end configuration accepts standard copper tube on both ends, allowing inline repair or extension of existing copper runs. Its wrot construction provides consistent wall thickness and reliable joint integrity in pressure-rated systems.
Designed as an OEM-style replacement and standard-service fitting for 1-1/4 inch nominal copper tube systems using C x C solder connections.
Installation should be performed by a licensed plumber in accordance with local plumbing codes and the IPC. Shut off and drain the water supply before cutting into any existing line. Clean and flux both pipe ends and fitting sockets thoroughly before applying heat and lead-free solder. Allow the joint to cool completely before restoring system pressure.
